We will proceed our step-by-step approach to detecting a pool heater by taking a look at what to do when the light in the command pad on the peak of your Sta-Rite swimming pool and health club heater that is identified “solution heating unit” is lit. (We will certainly temperature calibrators proceed with the assumption that you know everything from segment one.) This time you will certainly should take out the sides from the heating system just before detaching power to the heating unit so that you could check out the codes on the board connected to the topside. After eliminating the sides, you will certainly view the huge topside that is still attached to the heater. Listed below the topside is a steel panel that keeps the topside in position. Under this panel there are 2 securing pins (cotter pins). Meticulously remove the two pins and save them someplace protected up until reassembly. Delicately eliminate the leading and transform it inverted. You will certainly view a light lit on the board you are taking a look at when you turn the topside over. The light will certainly be close to a code that is created on the board.

The very first code that you'll see on the left side of the board will certainly be PS. This is the code for the stress switch. We covered the stress button in sector one. If this light is lit go back to segment one as well as review that section. If essential adhere to the instructions to switch out the tension button.

The next code you'll view on the board is HLS. If you have a controller on the technology you will certainly should bypass it at this time. You will have to very carefully disconnect the power from the heater. After you make sure that the power is disconnected, you will certainly need to discover as well as open the high-voltage closet. This cupboard is a steel box in the center of the heating system. If you are looking at the cupboard, there is typically a screw on the top ideal side. Loosen the screw as well as the door will swing down towards you. You have to be remarkably cautious when working in this box as well as simply doing this when you are sure that the power to the heating unit gets out.

You will need to bypass the firewall program security interface. To do this you will need a short cable with stab-tab ports. If you have a controller and also it was properly installed the cable might have been left in the box by the tech that set up the controller. If not you will need to make this jumper cord. At this factor search in your owner's manual to situate both proper pins to connect to. If you have a controller or are using a fire fighter's switch this is where your control needs to be linked. If you have a controller and it is not hooked up right here, maybe the source of your issues and also either have a certified tech fix the trouble or remedy it on your own.

You must make sure not to place the jumper cord on the power terminals or you will damage your heating system by burning up the electronic system. Usage your guidebook to situate where the firefighter's button is expected to be connected as well as meticulously connect your jumper in between these terminals. If you now turn on the power and also the heater functions without any issues, your problem lies in the controller or the wiring going to the controller. You will should trouble shoot this device.

If you still have the very same trouble with your heating unit. (“service heating unit” light comes on), leave the jumper in place and also confirm that the pump is on which you have good water circulation. Ensure once more with your meter that the stress switch is not cycling. It should check out as a dead short. (View section one) With good water circulation validated as well as the “service heater” light on, your trouble could possibly be among the thermo-regulators in the security technology.

Since we started this with the sign light on the board lit beside HLS, the very first food we are going to examine are the cords visiting the higher limit button. The high restriction button is situated near all-time low on the left side of the water manifold as you admit. To view it you should eliminate the side cover on the water manifold. The screw that holds the cover is on the best of it. You need to ensure that the orange wires going to the button are undamaged, attached and also not corroded. If the electrical wiring is good, utilize your multi-meter to examine that the high restriction button reviews as a dead short. If it checks out open as well as the water is not over 104 F, change the higher limitation button. If this does not repair your problem you may have a bad control board and also it will have to be changed. Testing the control board is a really involved process as well as will be handled in a later segment.

This is the end of sector 2 and also has actually taken you via part of the safety circuit in the heating system and 2 of the sign lights on the board. We will advance with our systematic diagnose of issues on the Sta-Rite swimming pool and medical spa heating system in the next segment.
